Honestly I don't think that there was anything that DH could have said or done that wouldn't have been annoying. He was actually really good, supportive, doing what I said without comment, rubbing my back, stopping when I snapped at him to stop. But I was just annoyed at everyone. So I guess the only advice I could give anyone, is to just BE there, do exactly what you're told (don't offer suggestions), agree with everything your wife/partneer says (but don't be patronising about it) and DO NOT take anything said or done to you by your other half personally (we may mean it in the moment when we tell you you are useless and that we hate you for putting us through this - but that moment WILL pass, and anyone going through the agony of labour deserves to be cut alittle slack. And no matter how joyous, exciting, or whatever other positive emotion / feeling birth is (or is supposed to be and was for me) it most definitely is agony.)
